MAGAZINE H EATING-STOVE.

SPECIFICATION forming part of Letters Patent N o.` 616,003, datedDecember 13, 1898. Application filed January 13. 1898. Serial No.666,546. (No model.)

diana, have invented certain new and useful Improvements in MagazineHeating-Stoves; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in Io the art to which it appertaius to make and use thesame.

This invention relates to magazine heatingstoves; and one object is toprovide a construction which will permit the easy convervI5 sion of anordinary form of heating-stove without a magazine into'one'with amagazine and that, too, without requiring any alteration in the parts ofthe ordinary heating-stove, but simply by the application thereto ofdetach- 2o able appliances.

Another object is to provide a novel relation of parts in amagazine-stove calculated to improve the operation of the same,economize in the use of fuel, and provide for better e5 regulation ofthe draft.

With the above-stated and other objects in view the invention consistsin certain improved features of construction and novel combinations ofparts specifically described 3o hereinafter and the essential elementsof which are pointed out in the appended claims.

In the drawings which accompany and form part of this specificationpreferred forms of embodiment of the invention are illustrated,

and of said drawings- Figure l represents a heating-stove in perspectiveadapted for the application of my improvements thereto. Fig. 2represents the same in central vertical section with the mag- Fig. 3represents the shell of the stove in plan with the cap thereof removedand the magazine in place within the shell. Fig. 4 represents themagazine in sectional bottom plan. Fig. 5 represents the complete stovein front elevation, with the magazine indicated in broken lines. Fig. 6represents the magazine in perspective removed from'the stove. Fig. 7represents the magazine in front elevation. Fig. 8 represents a combineddamper and lid in top plan.

In the drawings the reference-letter a designates the cylindricaloutside shell of the stove, which is contracted at its lower end, asshown at d', a grate b being provided at the base of said contractedportion and an ashpit c being suitably arranged below said grate andprovided with a door d, having an ordinary slide-damper. A door e isalso provided at the lower part of the contracted portion of the shellct to permit access to the upper side of the grate b. A cap f is appliedover the upper end of the shell d, being removable therefrom andcentrally apertured, as shown at f', which aperture is adapted to beclosed by a lid f2, having a register f3 of any suitable construction,and a smoke-Hue g rises from the capf at one side of the same, the inpterior of the shell a opening directlyinto said flue. In one side of theshell d, near the top of the same, there is formed a series ofdraftopenings h for the inlet of cold air, and a draft-regulator ordamper h is arranged in suitable guides on the exterior of the shell, soas'to control the amount of air admitted.

The arrangement of the above-described parts may be similar to that inan ordinary heating-stove, and in furtherance of the ob ject first abovestated I propose to suspend the magazine Within the stove-shell withoutnecessitating any change of construction in the latter. To this end themagazine e', which is of cylindrical form and closed at one end and openat the other, is equipped with a suitable number of hooks fi', each ofwhich is lpreferably formed of a piece of strap metal bolted or rivetedto the side of themagazine, bent outwardly therefrom and thence parallelwith the side of the magazine to form the shank of the hook, and thencedoubled upon itself to form. a hook which will take over the edge of thestove-shell. It will be seen that with such a construction of suspensiondevices on the magazine the latter can be easily suspended within thestove-shell, while at the same time the cap f can properly be applied,as clearly illustrated in Fig. 2. At an intermediate point nearer thelower end of the magazine a number of projections 712 are fastened-tothe sides of the magazine, so as to bear against the walls of thestove-shell and keep the magazine properly centered therein. It will beobserved that the closed top of the magazine is sufficiently loweredwithin the stove-'shell to have the openings 7L in the side IOO of thelatter extend above the plan of the top 0f the magazine. This particularrelation of parts permits a more effective use of the draftregulator ordamper h'.

The top of the magazine is formed with a central circular aperture j forcharging purposes, which aperture is closed by semicircular plates j',hinged to the under side of the magazine-top at oppositev sides of thesaid opening, said plates together constituting a complete closure forthe aperture, so that when the stove is in operation the gases arisingfrom the fuel cannotA escape without first passing downwardly throughthe fire. It is preferable to provide for the automatic closure of theopening in the top of the magazine after the fuel has been introduced,and to this end I secure weighted armsjz to the under sides of theplates j', the weightsj3 on the ends of said arms being so disposed asto have a constant tendency to throw the plates upwardly.

The operation of the stove will be apparent and therefore need be butbriefly described. The magazine having been charged with fuel and a firehaving been started on the grate l), such charge of vfuel burns at itslower portion, while that portion more remote from the point ofcombustion goes through a coking process in the magazine, and the gasesresulting therefrom having no outlet in the upper part of the magazineare forced to pass down through the re. This insures complete combustionand makes the stove in itself asmoke-consumer. Of course I am aware thatthis general idea is not new with me; but the particular novel relationof parts above described is believed to provide for a more effectiveoperation in a magazinestove than heretofore accomplished and tofacilitate regulating the same.

As a measure of safety I provide a gasescape port in the top of themagazine, and a valve 7s of a certain known weight rests by gravity oversaid port and keeps the same closed in the absence of excessivegaspressure within the magazine.

There the stove-shell has a door in its side, which is ordinarily thecase, I may provide the magazine with a side opening, and in thedrawings the letter m designates such an opening in the magazine, whichopening, it will be observed,is of somewhat greater height than theopening m in the side of the stove, with the object of preventing theissuance of smoke from the stove-door when starting the fire. It will beseen that the opening in the side of the magazine gives access to theinterior thereof through the openin g in the side of the stove, theobject of which is to facilitate building the lire. This opening in theside of the magazine is closed by a door n, which is hinged to openinward and is equipped with a latch n', adapted to engage a catch 'n2 onthe exterior of the magazine, whereby the said door is held closed tokeep the magazine air-tight when the stove is in full operation. A smallhole o is provided in this door n, through which hole a poker can beintroduced when necessary, and the hole when not in use is closed by aswingcover o'. The stove-door 1J may be of any suitable construction.

It is to be noted that the lower edge fi of the magazine extends intothe contracted portion of the stove-shell, and hence this lower edge ofthe magazine is separated by a comparatively narrow space from the wallsof the stove, the result of which is that free combustion takes placeover a very limited area of the bed of fuel and an economical use of thelatter is accomplished.

Itis evident that the construction herein shown and described issusceptible of variations which would naturally suggest themselves to aperson skilled in the art, and hence I do not wish to confine myself tothe forms of embodiment of the invention illustrated in the accompanyingdrawings.

XVhere a stove is built in the firstinstance to embody my improvements,the magazine may be permanently fastened to the shell instead oi' beingsuspended therein by detachable hooks.

Registers both in the top and side of the stove, as shown in thedrawings, are not necessary, and either may be dispensed with withoutseriously impairing the operation of the stove.

I'Iaving thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is-

l. In a heating-stove, the combination of a stove-shell havingdraft-openings in its sides at the top, a magazine having a closed topan d open bottom and a plurality of elongated suspension-hooksprojecting above the top and taking over the top edge of thestove-shell, the magazine when suspended within the stove-shell havingits top considerably below that of the latter and the hooks being solimited in number and dimensions and so distributed as to offer noappreciable obstruction to free communication between the space in theshell above the magazine and the space around the latter; and a capfitting over the top of the shell and having a smoke-flue.

2. In a magazine-stove, the combination of a stove-shell having anopening in one side, and a magazine suspended within said shell andhaving a side opening corresponding in location with the side opening inthe stoveshell, but of appreciably greater height than the same, andsuitable doors for said openings.

In testimony whereof I affix my signature in presence of two witnesses.
